 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

All, With the diminishing of Fruit Of The Shed I had a wake-up call. Not that my contribution to the Fruit was so much, but my contribution to TheBackShed was. I started investigating my legacy here, and wanted to store it in one place, so I could look it up later. It may not be interesting to anyone else, so please ignore this post if so.

@Volhout Much appreciated. I'd totally missed the DMX post. I have been looking at the wireless DMX devices which are quite inexpensive. Thinking that they can be used for a GP RS485 wireless link(?)  |

Hi PhenixRising, These are local archives. It was not posted on thebackshed. This is the code that generates the DMX signal. You need to add one logic gate to combine the break pulse and the UART signals. 'test COM port 2 for DMX512 transmitter 'uses GP4 as TX pin and GP3 as BREAK generator 'requires external AND gate (74HC08) to combine GP3 and GP4 into '1 signal to drive MAX485 driver chip. SetPin gp3,dout 'pin for BREAK generation Pin(gp3)=1 'default is high SetPin gp5,gp4,COM2 'open COM port (for TX only) Open "COM2:250000,S2" As #1 'at DMX speed, 2 stop bits DMX$="Hello"+Space$(200) Do Pulse GP3,0.1 '100us break Print #1,DMX$ 'send data Pause 100 'pause for trigger Loop The only thing you need to do is create the correct values into the DMX$ variable. This requires groups of 16 bytes for the typical DMX-16 compatible lights. A graphical application would need to be writter. Above code just show a way to generate the signals. Not a complete product. PicomiteVGA PETSCII ROBOTS |

That's a tremendous body of work Volhout, some of which I will certainly be using before too long. So I can only say Thank You Very Much for sharing your expertise. As a mere mortal, I don't have anything of great value to offer I'm afraid. My simple (mostly modelling) applications just turn lights on & off and run small DC motors etc. Nothing that others couldn't write in a few minutes but that is why MicroMites are so great really. They let programming numpties like myself do these things quickly and easily and then get on with other stuff. I get stuck quite a lot (often very simple mistakes) so ease of debugging is essential in my case... But I do like to look at other peoples work too and try to understand what's going on and that is very interesting in itself. So thank you again to all you clever folk who make this such an intersting site to visit and use. Regards, IanT |
